Genomic analysis compares ADHD-related genetic variants in Neanderthal and modern human samples

The frequency of genetic variants associated with attention-deficit/hyperactivity disorder (ADHD) has decreased progressively in the evolutionary human lineage from the Palaeolithic to nowadays, according to a study published in the journal Scientific Reports.

Mouse model mimics clinical course and pathology observed in COVID-19 patients

A mouse model of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reproduces features observed in human patients, researchers report May 26 in the journal Cell Host & Microbe.

Simple salt solution can help transport COVID-19 samples to testing laboratories

In a new peer-reviewed study appearing in The Journal of Molecular Diagnostics, published by Elsevier, investigators report that a simple salt solution commonly found in hospitals and clinical laboratories, phosphate buffered saline (PBS), can be used as a medium to reliably transport coronavirus-contaminated specimens to the testing laboratory for periods of up to 18 hours, which is often needed in busy clinical settings.

New data may help understand the evolution of Austrian SARS-CoV-2 strains

216 SARS-CoV-2 genome sequences have now been completed and released in the framework of the "Mutational Dynamics of SARS-CoV-2 in Austria" project from CeMM, the Research Center for Molecular Medicine of the Austrian Academy of Sciences, in close collaboration with the Medical University of Vienna, the Medical University of Innsbruck and the Austrian Agency for Health and Food Safety (AGES).

Chimpanzee communication provides clues to human speech-rhythm evolution

One of the most promising theories for the evolution of human speech has finally received support from chimpanzee communication, in a study conducted by a group of researchers led by the University of Warwick.

Study offers new insight into how cells fuse

Scientists have known for a decade that cells that fuse with others to perform their essential functions - such as muscle cells that join together to make fibers - form long projections that invade the territory of their fusion partners.

Research could help identify disturbances in the body's copper metabolism

In biology it is well-known that every living organism is triggered by the hereditary material or DNA that encodes various protein molecules, which in turn perform all the necessary biological functions and it might seem that nothing else is needed to sustain the life of an organism.

Study uncovers how protein inhibits the development of tumors in mice

Proteins are found throughout our cells and regulate a lot of biological processes that are important forour survival.

A key player in hepatitis A virus infection discovered

How hepatitis A virus manages to enter liver cells called hepatocytes and initiate infection had remained a mystery for fifty years until now.

Collagen maturation regulates PEDF availability, study shows

Cells are like tiny self-contained machines that are constantly fine-tuned in response to both internal and external signals. Some of these signals are induced by extracellular ligands, specialized proteins that bind to specific receptors on the cell surface, stimulating signaling pathways and altering gene expression.

UZH researchers develop new X-ray contrast agent for high-resolution vascular imaging

Various diseases in humans and animals - such as tumors, strokes or chronic kidney disease - damage the blood vessels. Capillaries, the smallest blood vessels in the body, are particularly affected.

Minuscule tracking devices give unprecedented peek into how cells change with time

For the first time, scientists have introduced minuscule tracking devices directly into the interior of mammalian cells, giving an unprecedented peek into the processes that govern the beginning of development.

The eye initiates an immune response in the lens after injury

The lens of the eye is an unusual organ. Unlike most of the body's organs, blood vessels don't reach the lens. If they did, they'd obscure our vision and we wouldn't be able to see.

Biophysicists determine the optimal age of reprogrammed stem cells

Biophysicists from the Moscow Institute of Physics and Technology and Vladimirsky Moscow Regional Clinical Research Institute have determined the optimal age of reprogrammed stem cells suitable for restoring heart tissue.

'Good' bacteria have a niche in our noses, study suggests

Beneficial strains of bacteria residing in our guts, genital tracts, and skin have been shown to play a role in human health, and now, researchers publishing May 26 in the journal Cell Reports suggest that some of these "good" bacteria also have a niche in our noses.

Warwick researchers discover how cells activate autophagy genes during fasting

As modern life-styles and high calorie diets drive the UK's obesity levels up, researchers from the University of Warwick have found how cells respond to fasting and activate the process called autophagy, which means a healthier lifestyle can be promoted to help people maintain a healthy body weight.
